Functions & arrays (cont.)

• Practice: arrfun1.cpp in prata.

  • Note, that the formal parameter n receives the maximum size of the array and the formal parameter arr receives the pointer to the start of the array.
  • Indexing works the same.
  • total = total + arr[i];

• I like the symbolic reference arr [ ] as the formal parameter because it reminds you that this argument points to an array!
